AT&T Nokia Lumia 900 (Ace) specs leaked ahead of CES unveiling

Nokia is getting ready to make a big Windows Phone-powered splash in the US, it seems. Right before 2011 ended, we showed you some leaked renders of the Finnish company’s upcoming WP flagship smartphone, the Lumia 900. This has also been known so far as the Nokia Ace, and it’s expected to be unveiled (at least a version headed to AT&T with LTE support) next week at CES.

But if you were anxious to hear something about the Lumia 900’s specs, you don’t have to wait until then. Most of the important stuff has been leaked today courtesy of PocketNow.

So, as previous rumors hinted, the Lumia 900 will have 4.3-inch touchscreen. Thanks to the current limitations in Windows Phone though the resolution will still be 800×480. The phone will have 512 MB of RAM, an 8 MP camera, and a pretty big 1,830 mAh battery. It will weigh 160 grams, 18 more than the Lumia 800.

What you see above is a mock up of the Lumia 900 alongside the Lumia 800, based on the leaked renders from December 30, and factoring in the leaked specs from today.

AT&T’s version of the Lumia 900 is codenamed Eloko, and it will interestingly ship with support for T-Mobile’s AWS 1700 MHz HSPA band as well. So while it’s not likely that the Lumia 900 will be sold by AT&T unlocked, some unlocking options are bound to crop up soon after its launch, helping those of you on T-Mobile make use of the superphone.

Despite what past rumors have claimed, the Lumia 900 won’t run Windows Phone Tango – the next version of Microsoft’s mobile operating system. It will however run Mango, which is the currently shipped OS. That’s interesting, because it was said at one point that Tango will bring LTE support. Now it seems likely that this will end up being baked into Mango.

The Lumia 900 will also be launched outside the US, so those of you who live elsewhere will be able to get your hands on it later this year.
